摘要:本次畢業(yè)設(shè)計的選題為南通市商務(wù)局綜合樓建筑給水排水工程設(shè)計。南通市商務(wù)局綜合樓,是一14層綜合性民用建筑,三層以下為商業(yè)用房,四層以上為住宅。該建筑東側(cè)及南側(cè)的城市道路旁,有一市政給水干管可做為該建筑物的水源;其管徑為DN300,常年資用水頭為18米,與樓距離20米,管頂埋深1.5米。城市排水管道在擬建建筑物北側(cè),其管徑為DN400,管頂埋深為2.5米,與樓距離20米。建筑附近有表壓為0.20MPa的蒸汽熱源。建筑給排水系統(tǒng)主要包含了建筑給水、建筑排水、消防給水和熱水供應(yīng)四個方面, 第一運用資料收集分類法和系統(tǒng)分析法對建筑給水、排水、消防、熱水四個部分現(xiàn)狀及存在的問題進行研究,提出具體的發(fā)展方向,第二運用案例剖析研究方法基于本次設(shè)計的背景資料選定方案,逐個計算。按照計算結(jié)果繪制平面圖、系統(tǒng)圖。本設(shè)計采用分區(qū)供水,一至三層為市政管網(wǎng)直接供水,四到十四層采用水泵水箱聯(lián)合供水。 關(guān)鍵詞 給水;排水;消防;分區(qū)供水
Abstract:The graduation design topic for building water supply and drainage engineering building of Nantong Municipal Bureau of Commerce design. The comprehensive building of Nantong Municipal Bureau of Commerce, is a comprehensive civil building 14 layer, three layer below for commercial buildings, four storeys for residential. City Road East and south side of the building, there is a municipal water supply pipe can be used as the building water; its diameter is DN300, all the year round the head of 18 meters, and the building of a distance of 20 meters, the top of the pipe buried depth is 1.5 meters. City drainage pipe in the building on the north side, the diameter is DN400, the top of the pipe depth is 2.5 meters, and the building of a distance of 20 meters. Building near the gauge pressure of steam heat source 0.20MPa. Building water supply and drainage system mainly includes the building water supply, building water supply and drainage, fire water and hot water supply of four aspects, first using the data collection analysis classification method and system method to research the building water supply, drainage, fire, hot water four parts present situation and the existence question, proposed the development direction of concrete, second use case analysis research method background the design based on the selected scheme, one by one calculation. Draw a plan, according to the calculation results of the system. This design uses the partition of water, one to three layers for the municipal water supply pipe network directly, four to fourteen layers of the water tank joint water supply.
